Ingame theory,Deadlock is a game where the action that is mutually most beneficial is alsodominant. This provides a contrast to thePrisoner's Dilemma where the mutually most beneficial action is dominated. This makes Deadlock of rather less interest, since there is no conflict between self-interest and mutual benefit.On the other hand, deadlock game can also impact theeconomic behaviour and changes toequilibrium outcome in society.
| C | D | |
|---|---|---|
| c | a, b | c, d |
| d | e, f | g, h |
Any game that satisfies the following two conditions constitutes aDeadlock game: (1) e>g>a>c and (2) d>h>b>f. These conditions require thatd andD be dominant. (d,D) be of mutual benefit, and that one prefer one's opponent playc rather thand.
Like thePrisoner's Dilemma, this game has one uniqueNash equilibrium: (d,D).
| C | D | |
|---|---|---|
| c | 1, 1 | 0, 3 |
| d | 3, 0 | 2, 2 |
In this deadlock game, if Player C and Player D cooperate, they will get a payoff of 1 for both of them. If they both defect, they will get a payoff of 2 for each. However, if Player C cooperates and Player D defects, then C gets a payoff of 0 and D gets a payoff of 3.
Even though deadlock game can satisfy group and individual benefit at mean time, but it can be influenced by dynamic one-side-offer bargaining deadlock model.[1]As a result, deadlock negotiation may happen for buyers. To deal with deadlock negotiation, three types of strategies are founded to break through deadlock and buyer's negotiation. Firstly, using power move to put a price on the status quo to create a win-win situation. Secondly, process move is used for overpowering the deadlock negotiation. Lastly, appreciative moves can help buyer to satisfy their own perspectives and lead to successful cooperation.
